Dpd is a delivery company which delivers packages all over the UK and from personal experience they are pretty good at making sure your package arrives on time and keep you update to the progress of the parcel. They track the parcel from start to finish and give you an accurate time in which it will end up at your door so you can make sure that you are there and don't miss the knock on your door. This is particularly useful and it helps that you're sent a text notifying you to the time in which they will arrive thus preventing one of my pet hates which is waiting around all day for people.
